Mercenaries and Private Military Companies
Mercenaries are combatants hired by state or non-state actors who are not part of a national military. Private military companies, or PMCs, formalize this model by offering security, training, and tactical services under contracts. Major firms include Academi, formerly Blackwater, and G4S, which operate globally in conflict zones and high-risk regions. The U.S. government has used PMCs in Iraq and Afghanistan, with oversight focused on contractor conduct and legal accountability. The International Code of Conduct for Private Security Service Providers, known as the ICoC, sets standards for human rights and the use of force, and companies like Triple Canopy and Constellis have joined this association. For an overview of private military contractors and their legal status, see the Bureau of Investigative Journalism overview of private military contractors and the law.
Mercenary and PMC operations intersect with financial risk, insurance, and compliance. Private military contracts are often funded through government budgets and defense appropriations, with major clients including the U.S. Department of Defense and NATO allies. The market for private security services has grown, with firms such as GardaWorld and Control Risks expanding their footprint in regions with instability. Regulatory frameworks vary by country, and the U.S. Department of State issues licenses under the International Traffic in Arms Regulations, or ITAR, for security-related exports and services. The U.S. Securities and Exchange Commission, or SEC, also monitors public disclosures from defense contractors and firms with government contracts. For details on SEC filings and contractor reporting, see the U.S. Securities and Exchange Commission EDGAR search page.
Spies and Private Intelligence Operations
Spies, or intelligence operatives, collect secret information for governments, corporations, or private clients. Private intelligence firms, sometimes called private eyes for hire, offer competitive intelligence, due diligence, and threat assessments. Companies such as Kroll, part of Duff & Phelps, and Stratfor, now part of R.R. Donnelley, provide open-source and human intelligence services to corporate clients. The line between private intelligence and espionage is legally sensitive, and firms must operate within domestic and international laws on data collection, privacy, and export controls. For background on private intelligence firms and their methods, see the Council on Foreign Relations explainer on private intelligence firms.
Private intelligence work relies on data analytics, cyber tools, and field investigations. Firms may assess geopolitical risks, corporate espionage threats, or executive protection needs for clients in finance, energy, and technology. The market for competitive intelligence and cyber threat services has expanded as companies face ransomware, supply chain attacks, and state-sponsored hacking. Major clients include Fortune 500 companies, banks, and law firms seeking due diligence on mergers and investments.

Private Eyes and Investigative Services
Private eyes refers to private investigators and detectives who conduct surveillance, background checks, and forensic accounting for legal, corporate, or personal clients. Licensed investigators operate under state laws in the United States, with requirements varying by jurisdiction. In financial investigations, private eyes often work with law firms, auditors, and regulators to trace assets, uncover fraud, or support litigation. Major firms in this space include Kroll, Pinkerton, and Control Risks, which combine investigative services with risk advisory and security consulting.
The private investigation sector intersects with cybersecurity, due diligence, and compliance. Investigators may analyze digital footprints, conduct open-source intelligence, or support corporate investigations into insider threats and embezzlement. For individuals, private eyes assist with missing persons cases, insurance claims, and family law matters. The industry continues to evolve with new tools for data analysis, digital forensics, and global investigations.
